CONTAINER BODY.

To all whom u may concern:

Be it known that-I, WILLIAM J. GULLEN,

a citizen of the United States, residing in' Joliet, in the county of Will and State of Illinois, have invented a new and useful Inuprovement in Container-Bodies v of which the following is a specification.

This invention relates in general to container bodies and has more particular ref- 10 erence to container or box bodiesconstructed of corrugated fiber board.

Aprincipal object of the invention is the provision of a new and improved connection between adjacent edges of such material in a box or container body or part.

Prior to my invention it has been generally the custom, in constructing boxes or containers of various shapes and sizes of corrugated board, to bring the adjacent ed-ges together and paste over them a cloth strip, one sometimes being pasted inside as Well as outside. Another method of connecting the edges has been merely to overla them and secure them in this position Wltll an adhesive.

Containers and boxes of this character are now replacing wood and metal containers to a considerable extent. Heavy materials may be packaged in them, as the board itself is readily constructed of suiiicient strength.

The means of fastening the ends together,

have, in the past, possessed far less strength than the strength of the corrugated board itself, and it IS an ob ect of this invention 85 to provide a connection for fastening the provision of such a connection which will give to the box a pleasing and finished appearance, and this without the utilization of more material than has heretofore been required and also without increasing materially the cost of production.

Other objects and advantages of the in vention will be apparent as it is better understood from the following description when considered in connection. with the ,ac

A further object of the invention is the' Specification of Letters Patent.

companying drawin illustrating a prej having the struction; v

Fig. 3is a partial enlarged section subparts separated to show the constantially in the plane 3-3 of Fig. 1; and

Fig. 4: is a smaller view but similar to Fig.

3 showing the relation of parts before con nection. The box shown on the drawing is of gen eral rectangular form and of corrugated board; although it will be manifest, however, that it may have other forms and be constructed of other material. In the pres.

ent instance the box is formed of a single sheet of material creased or scored transversely at 4: to define the side walls and provided with end flaps 5 adapted to constitute the ends of'the box. Three corners of the box in the present instance are formed at the score lines, the blank or sheet being told able on the score lines 4 to bring the box to the form shown in Fig. 2. The free vertical edges 6 and 7 are adapted to be connected together to finish the construction of the box, and it IS 1n the connection, of these edges that the present embodiment or my inven- 'tion is found. The central or corru ated ply 8 is removed from the edges 6 and and back a substantial distance to provide edge recesses 9 .at the edges 6 and 7, leaving the outer and inner plies 10 and ll spaced apart. A connecting member 12, composed in the present instance of a strip of corrugated board scored centrally throughout its length at 1.3,is provided. The corners 14% of this strip are rounded and the halves of it, setoil by the crease or scoring 13, are inserted respectively in the recesses 9 formed in-the edges 6 and7. Adhesiveisdeposited either upon the inner faces ot the outer plies 10 and 11 or upon both faces of the strip 12, v

the plies 10 and llb'eing pressed down to cause the adhesive 'to secure the parts together.

This provides a connection between theas Fig. 2 is a larger view of the same box edges of the container or box of strength substantially equal to the strength of the board, and of strength much greater than that provided by securing the edges together with cloth.

It is thought that the invention and many of its attendant advantages Will be understood from the foregoing description, and it will be manifest'that various changes may be made in the form, construction and material of the box and in the details of the connection between the edges Without departing from the spirit and scope of the invention or sacrificing any of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim:

1. A joint for corrugated fiber board boxes, said board comprising two outer flat layers and an intermediate corrugated layer, which consists of three sections of said board, the intermediate section being a bent .flap portion, and the other two sections beremoval of the corrugated layer from the outer elements of the joint and leaving intact the corrugated layer of theinner elements of the joint, the flat la ers of the outer elements being directly a bored to the flat layers of the inner elements.

2. A joint for corrugated fiber board boxes, said board comprising two outer flat layers and an intermediate corrugated layer, which consists of two sections of said board constituting contiguous sides of such box, and a separate intermediate flap portion uniting said sides, the corrugated layer of the said sides being removed where the flap is located, and the corrugated layer of the flap being left intact, and the inner faces of the outer flat layers of said sides being adhered directly t5 the outer faces of the said flag portion. igned in the presence of two subscribing witnesses. v
